logical Department. Much to his surprise, he found in the embryos 

 examined a gland which corresponded closely in position, general 

 appearance and to some extent in structure, to the hibernating gland 

 of lower Mammals. 



In this preliminary communication, a brief description will be 

 given of the position, appearance and anatomical relation of the struc- 

 ture in question, a histological description being reserved for a future 

 paper. 



The structure, which may be provisionally termed the inter- 

 scapular gland (glandula interscapularis), was constant in position 

 in all the individuals examined, including a foetus of 260 mm length, 



and four embryos 

 of 75 mm, 90 mm, 

 175 mm and 187 mm 

 respectively ^). 



In the adult 

 subject the writer 

 was unable to find 

 any trace of a gland 

 in a similar situation. 

 The gland is a 

 long, narrow paired 

 organ, lying partly 

 along the neck and 

 partly occupying the 



scapular region 

 (Fig. 1). It has no 

 anatomical connec- 

 tion with the thymus 

 gland. 



The gland can 

 conveniently be di- 

 vided into tw^o parts, 

 an anterior enlarged 

 portion and a post- 

 erior narrow portion 

 (Fig. 3). The former

1) For the measurement of the embryos, the writer has adopted 

 Prof. Minot's method ; that is, the embryo being measured in its natural 

 attitude, the greatest length along a straight line is given. The limbs, 

 however, are excluded from the measurements.
